1o Claims. (ci. 248-201) V downward pivoting of the burner, this hinge being designed in the fashion of an open support so that the burner could be removed by simply lifting same.

The present invention is directed to the same subject matter as the aforementioned French patent, but the means utilized therefor are still more eliicient and simple and ensure a considerable freedom of movement of the burner, notably when it is desired to move it to positions or inclinations permitting an easy access to the different component elements to be checked, repaired or replaced. Moreover, the same means also facilitate the movements of the burner when it is desired to remove same completely in relation to the front face of the generator.

The mounting constitutingk the subject-matter of `this invention is characterized mainly in that it comprises:

At least one burner-supporting` bracket secured to the l front of the generator;

A track provided on this support; l Rollers mounted on the burner and engaging the track; Stop or locking means for holding the rollers against movement at a predetermined point along the track, and, If desired, stop means for limiting the inclination of the burner in relation to its support, this kmovement to the predetermined inclined position resulting from the combination f two movements of the burner in relation to the front of the generator, that is,'a movement of translation and a movement of rotation wherein the bearing and fulcrum points are the aforesaid track-engaging rollers. According to a particularly advantageous embodiment of the invention, the mounting comprises two supports in the form of vertical brackets, disposed on either side of the burner, the burner being adapted to rock between the brackets when it is moved to the Vdesired inclined position, the brackets comprising `at their upper portion` a track bounded by front and rear stops and adapted to receive two pair-s of rollers mounted on the lower portion of the burner and disposed on either side thereof.V

According to a speciticfeature of this embodiment the stops limiting the stroke of the rollers-atthe end of the track are so disposed that they act at the same time as hinge means for one or the other set of rollers carried by the burner.

According to another feature of this typical embodiment, the aforesaid rollers are so positioned in relation to the burner body that the latter is constantly in a condition of stable equilibrium irrespective of the positions Vof the burner relative to its support. Y

Other features and advantages of the invention will rifa ICC

ing a burner mounted on the front wall of a generator in its operative position;

FIGS. 2, 3 and 4 are diagrammatic views similar to FIG. l which show three different inclined positions of y,

the burner in relation to its support. Y v

In the embodiment shown in FIG. lythe reference numeral 1 designates generally the burnerprovided with a handle 2, the front wall of a generator chamber adapted for mounting the burner being designated by the reference numeral 3. In the figures, 4 is the front end of a nozzle, 5 a burner mouth projecting into the generator chamber through an aperture (notches) in wallS, 6 a regulator unit and 7 an ignition transformer. Itis clear that'with known hinge mountings itis not possible to extract the burner mouth to a limited extent from the interior of the generator, the case being stopped after, a relatively short pivoting movement. On the other hand,-with known piv-4 and a movement of rotation, is utilized in the handling of the burner.

l To this end, the burner comprises on its lower portion f two pairs of like-sized rollers 8, 9 disposed on either sideV of the vertical plane of `symmetry of the burner, these rollers respectively engaging a pair of lateral supports 10 k(only one shown), constituting'apair of vertical brackets n secured on Athe front wall 3 of the generator and flanking the transformer 7. The two supports 10, consisting for example of pressed ribbed sheet-metal elements of substantial thickness, are `formed at theirV upper edges with tracks 11 (one shown) engageable by the pairs of rollers 8 and 9 (only one of each -being illustrated). tageously, the tracks 11 can be slightly inclined toward the front wall of the generator, so that the nozzles shown at 4 are directed slightly downwards, this arrangement facilitating the ilow of fuel thereto under all operative conditions. The sloping of the tracks also tends to maintain the front rollers 9j in positive engagement with the hook-shaped stops 12.

In the specific embodiment illustrated the tracks 1,1 are .l provided at their front end with hinge-forming stops'12` and at their rear end with hinge-forming stops 13, only .one each of thepairs of stops 12 and 13 on the symmetrically disposed supports 10 are illustrated. The separation of the roller pairs S and 9 is substantially lessfthan the spacing between the front and rear stops 12, 13.

In the operative position` the,V burner normally engages burner from its source of electric current, in order to appear asthe following description proceeds with reference to the accompanying drawing illustrating diagrammaticallyby way of example a typical embodiment of th invention. In the drawing:

FIG. 1 is a diagrammatical side-elevational view show-V avoid short Vcircuits and kprotect the voperator entrusted with fthe inspection or removal of one or. more component VYelements of the apparatus.

inFIG. l.

Patented Dec. 29,` l1964 Advan- Y In ythis operative Vposition the pair of rollersW 9 engage the hinge-forming v front stops 12 at the forward end of the track, asshown When the burner is stopped and the operator wishes to inspect the kburner head, he may iirst release the trigger-controlled locking device and `then pull the burner assembly backwardsby applying thereto a movement of translation in order to extract the burner mouth 5 from the generator and thus cause 4the pair of rollers S to engage the hinge-forming rear stops 13. A subsequent rotation of the burner assembly inthe counterclockwise direction yabout the horizontal axis `of the rear rollers 8 will then bring the assembly to the -position illustrated in FIG. 2. Fixed stop means such as an abutment 14,provided in the vertical brackets 10 directly underneath the rear stop 13,.Will limit the angular movement of the burner to a suitable position sufcient to permit a properV inspection of the burner head.` The stops 13, being hook-shaped, have formations 13 which overlie the rollers 8 (or 9) to prevent their lifting off the tracks 11 during the pivoting yof the burner.

It will be noted that in the case illustrated inV FIGS. 1 and 2 of the drawing the vertical line coincident with the center of gravity is so positioned that in either case the vburner assembly is in a condition of stable equilibrium. Thus, the center of gravity 15, whose normal Ylocation isintermediate the roller pairs 8 and 9,' swings past the rear rollers 8 as the burner is pivoted into the position of FIG. 2.

However, it is also possible as shown in FIGS. 3 and 4, after the burner assembly has been moved through only a part of its backward movement of translation, to lift this assembly slightly from the rear (Le. to swing it clockwise) and to free the rollers 8 from the rear hinge-forming stops`13. Under these conditions, and if the movement of translation is thereupon continued tothe rear, the rollers 9 will engage vthe rear hinge-'forming stops 13. Having thus completed its stroke, the' burner assembly can be rotated in the clockwise and the counter-clockwise direction to the positions shown in FIGS. 3 and 4,

respectively. It will be noted that in the two cases illustrated in these figuresv the stop 14 acts likewise as Va means for limiting the inclination of the burner assembly, on-being engaged by a surface 1 rformed by a botf tom edge of the burner body,` anda vertical plane passshown and described herein; thus, notably the design of the supports 10 may be modied by substituting therefore, for example, lateral rails or races carried byrinteriitting anges or ythe like.

maybe replaced by a singlesupport consisting either of Similarly, the two supports a lower intermediate rail or of an upper central rail. Besides, curvilinear tracks may be substituted for therrectilinear ones ilustrated, to provide variable positions kof the guide rollers during the movements of translation and rotation. Thus, for example, the roller-engaged tracks may consist of parallel-edged slots or'like elongated aper- Y tures formed in fiat 'sections of general curvilinear configuration, suitable stop means being provided thereon for holding the rollers in said apertures or slots against motion in the desired and proper positions.` In this case,

ithe number of pairs of Vrollers may be greater than two.

Besides, the iixed stops 14 for limiting the rocking movement of the burner assembly-may be dispensed with, so that the assembly may berocked .to the maximum extentY Vin the clockwise Vand counter-clockwise directions. Y Y 1 Furthermore, he supports 1t)Y may be-extended ver- 4 l tically to constitute a protective casing enclosing the greater portion of the burner assembly.

On the other hand, although inthe embodiment illustrated the supports 2 are secured on the front wall 3 of the combustion chamber of a generator, it would not constitute a departure from the principles of this invention to provide supports secured directly in the underlying ground or door.

Finally, the position of the handle 2 is arbitrary, for it could as well be secured in any other position on the burner assembly, for example in a horizontal plane instead of a vertical plane.
